today I setout some striglines, to find where the walls would sit on top of our foundation so we could place reid bar starters in, it was a bit of a test to hwt it right, as Dutchiw forgot to take off the offset off the measurements he gave me, and one of the part timers set some of the profiles up wrong, once i figured it out I rand 6 by two in the right place to use as a setout guide and marked out for the starters. I have worked on numerous Demolition jobs in the past two I remember was the Karen Walker shop in Newmarket and at the University of Auckland marine biology new build in Leigh. (Dismantling old toilet blocks) At both jobs I secured the perimeter by putting up danger tape.
The work was not notifiable because:
There was no drop risk
There was no asbestos present
We did not have to erect or take down scaffold.
Or we did not have to use Oxygen.
Once the site was taped off, and out of bounds I proceeded by removing the roof first, I made sure there was no fall risk and used props if needed I also put effort into making sure I had an empty skip bin and I was not leaving nails out or any sharp objects. I used a sabre saw, a pry bar and a sledge hammer to remove walls in a safe manner. Getting help to lift and remove material where needed. I also made sure the plumbing and electrics were redundant.
Another more recent Demoltion job, I recall was the Whirinaki school that I did with Brian we applied the same principles.
Formwork
I have worked on numerous formwork projects. I did a lot for HEB construction: this included a 400 metre long retaining wall at the Greville road intersection in Albany. At the same job we also boxed up and poured gantry bases for massive over the road, road signs. Please consult Craig Munday 027 273 738. The retaining wall consisted of ramming reid bars into a sloped excavated bank, and then digging a foundation for the walls and tying the steel, we then poured the foundation and landed precast concrete panels, they where installed on an angle and locked to the reid bar with a figure 8 type anchor bolt, we then grouted behind the wall, installed pef rod between joints and ran sika f in the joins. Then we placed cages and poured behind and formed an above ground gutter that ran the length of the wall. Since working for Alpha I have boxed up and tied steel and poured the chimney at the Helensville job for Chris and Lousie, tied the reinforcing for the driveway at Lupton, boxed up and poured the nib wall for the retaining wall at Lupton (as well as helping build that retaining wall the concrete block one and the timber one ) and am currently working on tying and installing the formwork at the Ngawha power plant.
Roofing
The first roof I ever worked on was in Algies bay, circa 2015 it was a 3 degrees pitched flat Skillion type roof on an architecturally designed home. I was self employed and self contacting to Cookie Cutter construction. Tim Barnes 0211843344. We installed Posi struts which came delivered, we man handled them up and secured them with tech screws. After marking out appropriately. We had to box up internal gutters and the external corners with framing and plywood like a nib wall. The whole roof surface was then lined with plywood. Much in the fashion of doing a floor and then it was water proofed with Butanol torch on. We also had to make sure there was no nails sticking up so it wouldnt interfere with the butanol before it was laid and therefore preserve the weather proofing. I was working with Steve who later got me the job with Alpha. Brian knows him I do not have his number.
The second roof I worked on in 2018 was a hip and valley industrial roof at The Oaks retirement village for Alpha Construction, me and Nathan Cutforth marked out for all the trusses and labelled them according to the plan. We landed the trusses on the top floor on top of the walls (craned). Then manhelded them into place and braced them. The valleys, where also formed by the pre-made trusses and some jack rafters. I also helped build the building b roof, but by then we had way more staff there. There were cpc 80s installed at every spot where the trusses were landing on a wall. And we ran purlins on top at 600 centres.
The third roof I worked on was the Kaikohe steel frame job in 2019, again for Alpha, the trusses came on a hiab, we stored them properly and then carried them up. It was a hip and valley style roof. The trusses ran in different directions around the perimeter to form the roof plus to shape the hip and valley. We secured the trusses with propriety tech screws. And braced them with steel rondo. They also had proprietary type brackets that we installed where the trusses landed on walls and we used the rondo type steel to run purlins. They had there own type of steel flashings for the valleys
Later in 2019 we worked on the Warkworth primary school job. The roof was all steel beam portals but we extended the eaves out with ten by 2 timber and screwed straight thru from the top down to secure to the existing steel with special Wurth screws we had to countersink the timber to acheive this, and we also screwed thru the timber sideways into the steel , I personally marked out an entire side about 30m. This was then framed up and used to form the facia and soffit. Later on I assisted in helping Nathan line the soffit with hardies soffit lining and plastic jointers with a ten mil negative detail on both sides.
We also did soffit lining and facia previously together (myself and Nathan) on the carport at the modular homes in auckland.
I have also worked on a poured concrete roof and a heeble block construction please contact sese on 0211910118Please get in contact if you have any questions.
